The angles between the projection of the axes in
dimetric projection renders two of the three to be equal. To draw
the outline of an object in dimetric projection, two scales are
required. The scales are generated the same as for isometric. An example of how to construct
the two scales is shown below.

Two of the angles between the projection
of the axes are equal. Thus two scales are required. The
following animation shows how the scales are generated.
